Sorry to be off topic, but I am curious what he will be doing in the very near future. He has been running OpenAI for many years, and no matter what the reason for his leaving, I think he deserves some serious down time to do a personal refresh.
He is a major investor in a few high profile startups, like Humana’s AI Pin, so either he just wants new challenges, or there is some form of scandal (let’s all hope not), or there are issues on not going full steam ahead in profitability.
